Look at netmichelle's photos and you will get a clue about her fascination with the LARGEST organ of the human body . . .

the skin!

Meet with her and I imagine one would fully understand her fascination.  

the skin can affect almost all senses of the human body.

the eyes. . . . as a canvas
the nose. . . from the oils and sweat
the taste buds . . .  I love the taste of skin
and touch. . . scratching and caressing

I haven't figured out one for hearing yet, but if anyone can, it will be netmichelle. (Bradbury could write a novel about her called "The Illustrated Woman".)
